The Nano3LR1 is a compact 3″ 3D print drone, weighing around 100g. It features a 1S Li-Ion battery that provides a flight time of approximately 20 minutes with a 40% reserve. With its lightweight design and powerful brushless motors, the Nano3LR1 offers stability and precise control. Additionally, its 3D-printed frame allows for customization, making it a versatile choice for aerial enthusiasts.
This drone features an all-in-one (AIO) 5in1 board that combines the receiver, VTX , ESCs and FC into a single board. The advantage of this setup is that it keeps the drone as lightweight as possible and simplifies the assembly process.

Based on my experience, my recommendation would be to use ABS for printing the drone. ABS’s UV resistance and added stability in crash situations make it a suitable choice. However, please keep in mind that PLA is also a viable option due to its hardness and ease of printing. Ultimately, the choice depends on your specific requirements and preferences.
I used Cura 5.2.2 as my slicing software for the printing process.
Important! Union Overlapping Volumes must be set!
